ONLINE deals service LivingSocial says its website was hacked, and the personal data of more than 50 million customers may have been affected.

The company said today that customers' names, email addresses, dates of birth and encrypted passwords may have been compromised by the cyber attack.

But it said the database that stores customer credit-card information was not accessed or affected.

The Washington DC-based company said it was working with law enforcement officials to investigate the attack and was contacting customers in nearly all of the countries where it operates.

A banner on its website today read: "Important notice for customers. If you haven't already updated your LivingSocial password, please update it now."

In an email to customers, company chief executive Tim O'Shaughnessy requested that users reset their passwords, and he reminded them to disregard any emails claiming to be from LivingSocial that seek personal or account information.

"The security of your information is our priority," he wrote.

"We always strive to ensure the security of our customer information, and we are redoubling efforts to prevent any issues in the future."

The company did not immediately explain how the hacking occurred, except to describe it as a cyber attack that "resulted in unauthorised access to some customer data from our servers".

It's the latest bad news for LivingSocial, which offers deals on everything from restaurants to spa sessions.

Last November, the company announced it was cutting 400 jobs worldwide, or about 9 per cent of its workforce, as the deals marked continued to face challenges.

In recent years, online deals have gone from fad to a much-copied business model that's easy to set up but difficult to sustain.
